issue 35 solved.
35) change User.api_gifts to include api_gifts.deleted_at information.
    User.api_gifts. Sort not deleted api gifts before deleted api gifts
    that is - ajax remove gift from gifts/index page in util.new_messages_count
    "partial" delete gift when closing/deleting user account
    testcase:
      provider 1 = google+, provider 2 = facebook, user a = Gofreeerv A (google+) + Jan R (Facebook), user b = Jan R (facebook)
      user a (provider 1+2) creates gift x
      user b friend with a (provider 1) loads gifts/index page and sees gift x
      user a deletes provider 1 account
      gift x should be ajax removed from user b's gifts/index page
      user a should still se gift x in gifts/index page
issue 36 solved. solution: added comment.partial_deleted?(login_users) method to partial deleted comments to be ajax removed from gifts/index page

36) change util/new_messages_count to include delete marked api comments
    that is - ajax remove comment from gifts/index page in util.new_messages_count
    delete marked comment for one and only provider when user account is deleted
